Study on the possible molecular states composed of ${\Lambda }_c{\bar{D}}^{\ast }$, ${\Sigma }_c{\bar{D}}^{\ast }$, ${\Xi }_c{\bar{D}}^{\ast }$ and ${\Xi }_c^{\prime }{\bar{D}}^{\ast }$ in the Bethe-Salpeter frame based on the pentaquark states $P_c(4440)$, $P_c(4457)$ and $P_{cs}(4459)$

The measurements on a few pentaquarks states $P_c(4440)$, $P_c(4457)$ and $P_{cs}(4459)$ excite our new interests about their structures. Since the masses of $P_c(4440)$ and $P_c(4…
